Coding for pre-schoolers: a ‘Turtle Logo’ in Forth

*New!* (26 Nov) – Turtle Logo v1.4 is available now! Entirely key operated, suitable for 3-4 years+ to 99 years. 750 lines of Forth code. Algorithmic drawing program with advanced features, incl. macro record & playback, color, etc. Works on WinXP to Win10.

1. Inspiring the next generation of technology builders.

A challenge faced by both parents and teachers is how to help young children develop a ‘builder’ relationship with technology, instead of becoming increasingly passive consumers of content created by others. The consensus on what’s important for older kids and adults is clear: coding. This enables children to participate in the creation of their own technological “micro-worlds” — environments rich in educational potential.[14]

This autumn, spurred by having our own young children (one aged 4 years, the other 16 months), we began an experiment, the result of which is a Turtle Logo program for Windows computers (freely downloadable) that is simple enough to be accessible for children from 3 years and older, while providing an extensible platform that can grow with the child.

The long-term goal is to enable children to express their creativity, artistry, and natural ‘builder’ impulses using coding, computer graphics, and robotics as readily as the previous generation could using paints, brushes, and building blocks.

A Radar Tracking Approach to Data Mining

(Statistics and Data Mining II)

Automated decision problems are frequently encountered in statistical data processing and data mining. An heuristic filter or heuristic classifier typically has a limited set of input data from which to arrive at a set of conclusions and make a decision: REJECT, ACCEPT, or UNDETERMINED. In such cases, pre-processing the input data before applying the heuristic classifier can substantially enhance the performance of the decision system.

In this article, I’ll motivate the use of a radar-tracking algorithm to improve the performance of automated decision making and statistical estimation in data processing. I will illustrate using the website visitation statistics problem.
